Explain why hexadecimal is used by computer scientists

Mathematics

Hexadecimal<span> numerals are widely </span>used<span> by computer system designers and programmers. As each </span>hexadecimal<span> digit represents four binary digits (bits), it allows a more human-friendly representation of binary-coded values. One</span>hexadecimal<span> digit represents a nibble (4 bits), which is half of an octet or byte (8 bits).

           
  
            " </span>The main reason why we use hexadecimal numbers is because it is much easier to express binary number representations in hex than it is in any other base number system." - http://digiassn.blogspot.com/2006/02/why-do-we-use-hexadecimal.html

Answer:

Step-by-step explanation:

Since we are not given the value of P, |Q|, R and S, we can as well assume values for them for the sake of this question.

Let P = 5, |Q| = 6, R =7 |S| = 2

Note that since Q and S are in modulus sign, they can return both positive and negative values.

P+Q = 5 + 6 (note that the positive value of Q is used since we need the greatest value of P+Q)

P+Q = 11

Hence the greatest value of P+Q is 11

For the least value of P+Q, we will use the negative value of Q as shown

P+Q = 5+(-6)

P+Q = 5-6

P+Q = -1

Hence the least value of P+Q is -1

Similarly:

R+S = 7 + 2 (note that the positive value of S is used since we need the greatest value of R+S)

R+S = 9

Hence the greatest value of R+S is 9

For the least value of R+S, we will use the negative value of S as shown

R+S = 5+(-2)

R+S = 5-3

R+S = 2

Hence the least value of P+Q is 2

NOTE THAT THIS ARE ASSUMED VALUES. ALL YOU NEED IS TO PLUG IN THE VALUES OF P, Q and R THAT YOU HAVE IN CASE THE VALUES DIFFERS.

zheka24 [161]

9514 1404 393

Answer:

  all 4 acute angles: 15 degrees

  all 4 obtuse angles: 165 degrees

Step-by-step explanation:

The sum of same-side interior angles between parallel lines is 180°. The smallest of them will be 3/(33+3) = 1/12 of 180°, or 15°. The largest will be 180° -15° = (33/3)(15°) = 165°. All remaining angles are congruent to one or the other of these.

  All four acute angles are 15°; all four obtuse angles are 165°.
